1 WINDMILL-POWEB SAVER.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed February 6,1908. Serial No. 576,378.

To all whom it may concem:

Be it known that I, JOHN R. BYRNES, a

Hutchinson, in the county of Reno and State of Kansas, have invent'dcertain new and useful Improvements in Windmill-Power Savers, of whichthe following is a specification.

My invention relates to means for saving the power of wind mills and theobject of the invention is to provide a power saver v which may bereadily attached to the tower and the strength of which being overcomeby the downward thrust of the pump rod will aid or assist in raising thepump-rod with the load thereon.

With this end in view, the invention consists in the novel construction,arrangement and combination as will be hereinafter more fully describedand claimed.

The invention will be more readily understood by reference to theaccompanying drawing which forms part ofthe specification, and in whichFigure 1, is a view in elevation, partly in c section, showing .thetransmission device.

Fig. 2 is a front elevation and Fig. 3, is a view of the lifting arm.

Similar numerals of reference indicate corresponding parts in theseveral views of the drawings. i

1 indicates the tower and 2 the pump rod which may be of ordinaryconstruct-ion.

According to my invention, I provide a rotatable frame 3 which isprovided with a head 4 adapted to rotate in the collar 5 which is a partof the tower and provides a turntable for the head of the frame. Thehead and collar are both provided with an opening through which thepump-rod can reciprocate. I form integral with the frame andapproximately L-shape, 'arms or supports 6, 6. The frame 5 is alsoprovided with bearings 7 and 8 in which the wind wheel shaft 9 isjournaled and upon which I secure two small pinion wheels 10 and 11. Ialso form bearings 12 and 13 on the frame 3 which support the shaft forgear wheels 14 and 15 in order that the gear wheels will mesh with thesmall pinion wheels. The gear wheels are connected by a rod 16, to

shaft, a lifting rod which one end of a itman rod 17 is connected. Inthe top 0 the arms 6, 6, I provide bearings 18, 18. A lifting arm 19having'lugs 20 which seat in the bearings 18, 18 is pivotally connectedat its opposite end to the upper end on the pump-rod. The lifting arm issecured at 21 to the upper end of the pitman rod 17. The lifting arm isprovided with a lug 22 formed integral therewith near the bearing lugs20.

At the base of the arm 6, 6, I form a lug .23 having an aperture thereinand a collar 25 secured thereon and upon which one end of a spiralspring 24 is seated. I secure the other end of said s ring over the lug22 on the lifting .rod, an by changing the pin 2:) in the aperture ofthe lug, the tension of the spring may be increased. The spring is ofsufficient tension to overcome the force that is exerted by the windwheel in depressing the pump-rod, and therefore upon the upper stroke ofthe rod, the spring will be exerted to help raise the load on the pumprod, and prevent the jerking and Vibrating of the same. Y I

It will beunderstood that the spring 24 is adjusted with reference tothe height of the column of water to be lifted and also to the Wei ht ofthe volume of the water raised by t e pump-rod.

The operation, construction and advantages will, it is thought heunderstood from the foregoing description, It be1ng noted that variouschanges may be made 1n the proportions and details of construct1onw1thout departing from the scope of the invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent is Ina device of the character described, awindmill tower, a turntable securedon the tower, a frame provided withL-shaped arms rotatabl mounted on the turntable, a Wmd wheel shaftjournaled on said frame and provided with inion wheels, gear wheelscarried by the v with the pinion wheels on the wind wheel ivotallysecured to the upper ends of the ll-shaped arms of the frame at one endand having its opposite ame and adapted to mesh end connected to thepump red, as pitman rod secured at one end to the gear wheel and havingits opposite end conneetedl to thelifb ing rod, a lug formed integralwith the lifting rod, a splral spring having one end seated on the framebetween the base of the arms and its opposite end; secured over the lugon the lifting rod and means for increasing .the

tension of the sp as and for the purpose set forth.

In teston. whereef I aflix my siature in presence 0 two witnesses.

JOHN R. B 'NES.
